JULIUS A. JEAN, OF DENVER, COLORADO, ASSIGNOR OF ONE-HALF TO GEORGE A. MOORS, OF DENVER, COLORADO.

AMALGAIVIATOR AND CONCENTRATOR.

Specification of Letters Patent.

Patented. March 12, 1907.

Application filed January 18,1906. Serial No. 296,661.

To all whom it may concern:

Be it known that I, JULIUs A. JEAN, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Amalgamators and Concentrators; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in amalgamators and concentrators for separatmg ores.

The object of the invention is to provide a separator of this character over which the ores in a ground or pulverized state are passed by means of the jarring or bumping of the amalgamator table or frame.

A further object is to provide means whereby said frame or table may be swung and bumped.

With the above and other objects in View the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is a side elevation of an amalgamator and concentrator constructed in accordance with the invention. Fig. 2 is a rear end elevation of the same, and Fig. 3 is a vertical longitudinal sectional view.

Referring more particularly to the drawings, 1 denotes a supporting-frame consisting of vertically-disposed cornerposts or standards 2, to Which are connected longitudinallydisposed side bars 3 and transversely-disposed end'bars 4. The upper ends of the corner-posts or standards 2 are further connected by end tie-rods 5.

On the inner side of each of the cornerposts or standards 2 are secured inwardlyprojecting brackets 6, with which are loosely and adjustably connected the upper ends of supporting rods or hangers 7, the lower ends of which are pivotally connected to the side bars 8 of an amalgamator-frame 9. The side bars 8 are connected by cross-bars 10 and at their rear ends are secured upwardlyprojecting flanges 12, to the upper ends of which and to the forward ends of the side bars 8 is connected the curved amalgamatortable 13, in which is formed a series of transversely-disposed rifiies 14. The table 13 is preferably formed of copper and transversely-extending rifiies 14, all formed therein to contain mercury. The table 13 is supported by segmental or curved side bars 15 and by diagonally-arranged side braces 16.

Secured to the lower side of the cross-bars 10 of the amalgamator-frame is a centrallydisposed bumping-beam 17, on the forward end of which is placed a metal cap 18, whereby said end is protected. On the upper side of the beam 17, near the rear end thereof, is secured a tripping box or frame 19, in the rear end of which is adapted to be arranged wearplates 20. Mounted in suitable bearings on the supporting-frame 1 adjacent to the rear end of the same is a transversely-disposed operating-shaft 21, on which is secured a centrally-disposed double cam 23. Said cam is adapted to operate in the tripping-box 19, whereby when the shaft 21 is operated the oppositely-disposed cam-faces 23 of the cam 22 will alternately engage the wear-plates in the trip-box, thereby moving or swinging the amalgamator-frame rearwardly. As each cam-face 23 passes or becomes disengaged with the wear-plate in the tripping-box said frame willl swing forwardly, causing the capped forward end of the bumping-beam to strike a suitable obstruction, causing the amalgamator-frame to suddenly stop, thus imparting to the same a jar, which will cause the ore on the surface of the table to move forwardly over the ripples therein. The shaft 21 may be provided on one end with a band-pulley 24 or other operating medium.

An amalgamator and. concentrating-machine constructed as herein shown and described may be employed for separating gold or other ore from sand, placer ground, or from the products of a stamp or other mill either in a wet or dry form.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined by the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A separator of the character described comprising a supporting-frame, a swinging frame loosely mounted therein, an outwardly-curved amalgamating and concentrating table arranged on said frame, riffles formed in and extending transversely across said table and means to swing said frame, a bumping-beam connected to said frame and a stop or obstruction for said bumping-beam, substantially as described. Y

2. In a separator of the character described, the combination with a supporting-frame having upright corner-posts provided with supporting-brackets, of a swinging frame, hanger-rods pivotally connected at their lower ends to said swinging'frame and adapted to be loosely engaged at their upper ends l with the brackets on said corner-posts, a curved amal amatin and concentrating table supported on said swinging frame, transversely-disposed riffles formed in said table adapted to contain mercury, a bumpingbeam secured to said swinging frame, a tripping-box secured to said bumping-beam, wear-plates arranged in said box, anoperating-shaft, and a double cam mounted thereon to engage the wear-plates in said box and thereby swing said amalgamatingframe in one direction, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IlGSSGS.
